Singing girls

The girls were singing together for about 5 minutes before I went to video them. It never fails that once they notice me videoing them they stop whatever it was they were doing. You can't tell what they are singing but they apparently know what they are saying to each other. I even tried to get them to sing Twinkle, Twinkle Little Star, but Layne was sure to let me know that she was NOT going to sing that song and continued with the one on the video.
